481725-63-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 481725-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,1,7,2 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 481725-63:
(8*4)+(7*8)+(6*1)+(5*7)+(4*2)+(3*5)+(2*6)+(1*3)=167
167 % 10 = 7
So 481725-63-7 is a valid CAS Registry Number.

Zirconium-Salan Catalyzed Enantioselective α-Hydroxylation of β-Keto Esters

Chen, Jie,Gu, Haiyang,Zhu, Xueying,Nam, Wonwoo,Wang, Bin

, p. 2976 - 2983 (2020/07/06)

We report herein the development of enantioselective and scalable α-hydroxylation of 1-indanone-derived β-keto esters by Zr(IV) complexes bearing readily available C2-symmetric salan ligands and cumene hydroperoxide as an oxidant, affording synthetically valuable hydroxylation products in high yields (up to 99percent) with excellent enantioselectivities (up to 99percent ee) under mild reaction conditions. In mechanistic studies, we have shown that (1) a Zr(IV)-salan complex was generated in situ as the active catalyst responsible for the chiral induction, (2) the transfer of the electrophilic fragment from cumene hydroperoxide to the Zr(IV)-bound enolate was accompanied by a heterolytic O?O bond cleavage, and (3) the formation of hydrogen bond between the amine hydrogen atom(s) of the salan ligand and the hydroxy group of cumene hydroperoxide was significant for stabilizing the stereocontrolled transition state and improving the enantioselectivity.

Group 4 metal complexes with new chiral pincer NHC-ligands: Synthesis, structure and catalytic activity

Zhao, Ning,Hou, Guohua,Deng, Xuebin,Zi, Guofu,Walter, Marc D.

, p. 8261 - 8272 (2014/06/09)

Chiral group 4 NHC-metal complexes were prepared in good yields by amine elimination from M(NR2)4 (M = Ti, Zr, Hf; R = Me, Et) and chiral pincer NHC-ligands, L4 (L4a and L4b), L5 and L6, which are derived from (S,S)-diphenyl-1,2-ethanediamine. Treatment of M(NR2)4 with 1 equiv. of L4 in THF gives, after recrystallization from a benzene solution, the chiral titanium amides (L4)Ti(NMe2)(Br)(THF) (7) and (L4)Ti(NMe2)(Cl)(THF) (11), zirconium amides (L4)Zr(NMe 2)(Br)(THF) (8), (L4)Zr(NEt2)(Br)(THF) (10), (L4)Zr(NMe2)(Cl)(THF) (12) and (L4)Zr(NEt2)(Cl)(THF) (14), and hafnium amides (L4)Hf(NMe2)(Br)(THF) (9) and (L4)Hf(NMe 2)(Cl)(THF) (13), respectively. Similarly, the reactions of L5 or L6 with 1 equiv. of M(NR2)4 yield the titanium amide (L6)Ti(NMe2)(Cl)(THF) (16), the zirconium amides (L5)Zr(NMe 2)(Cl)(THF) (15), (L6)Zr(NMe2)(Cl)(THF) (17) and (L6)Zr(NEt2)(Cl)(THF) (19), and the hafnium amide (L6)Hf(NMe 2)(Cl)(THF) (18), respectively. Complexes 7-19 were characterized by various spectroscopic techniques and elemental analyses. The molecular structures of 10 and 14-19 were also established by X-ray diffraction analyses, which represent the first example of the structurally characterized group 4 chiral NHC-metal complex. Furthermore, 7-19 are active catalysts for the polymerization of rac-lactide in the presence of isopropanol, leading to the heterotactic-rich polylactides. the Partner Organisations 2014.
